Levels of Measurement

Front

What are the four levels of measurement?

Back

Nominal, Ordinal, Interval, Ratio

Front

Define nominal level of measurement.

Back

The nominal level of measurement classifies data into distinct categories without any order or ranking.

Front

Define ordinal level of measurement.

Back

The ordinal level of measurement classifies data into categories that can be ranked or ordered, but the intervals between the ranks are not necessarily equal.

Front

Define interval level of measurement.

Back

The interval level of measurement involves numerical data where the intervals between values are meaningful, but there is no true zero point.

Front

Define ratio level of measurement.

Back

The ratio level of measurement has all the properties of interval measurement, and also includes a true zero point, allowing for the comparison of absolute magnitudes.

Front

What type of data is represented by the temperature in degrees Celsius?

Back

Interval level of measurement.

Front

What type of data is represented by the temperature of the body in Kelvin?

Back

Ratio level of measurement.

Front

What is a qualitative variable?

Back

A qualitative variable is a variable that is not numeric and represents categories or qualities.

Front

What is quantitative data?

Back

Quantitative data consists of numbers representing counts or measurements.

Front

Give an example of nominal data.

Back

Types of fruits (e.g., apples, oranges, bananas).
